Twitch today announced the Twitch Mobile Software Development Kit (SDK), which will eventually let mobile device gamers capture, archive, and live-broadcast their games to Twitch, a social network for gamers that already has a large presence on consoles and PCs. Android and iOS device owners have access to the Twitch community through a dedicated mobile app, but it allows only for viewing and interacting with content that's already been posted to the site. For mobile gaming fanatics, things are about to get a whole lot more interesting.
